WATER-FILTER.

specification of Letters Patent.

Application filed December 2, 1904:. Serial No.` 235,136.

To @ZZ whom it may concern:

Be it known that I, JOSEPH G. SUTTON, a citizen of the United States,residing in Seneca,

in the county of Newton and State of Missouri, have invented certain newand useful Improvements in Water-Filters, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to that character of water-filters adapted to beconnected to house water-service pipes for the purpose of supplyinghousehold needs for filtered water, the object of the invention being tomake a filter of simple construction and one in which thefilter-cylinder may be readily withdrawn from the case in which it seatswithout the water present in the filter-case being withdrawn with thefilter-cylinder, but linstead being allowed to discharge from the lowert end of the case.

Figure I is a vertical section taken through my filter. Fig. II is across-section taken on line II II, Fig. I. Fig. III is a verticalsection of a modified form of my filter.

1 designates the case of the filter, which is preferably of cylindricalshape. The upper mouth end of the cylinder is open and the lower oroutlet end ofthe cylinder is contracted to' furnish a funnel-shapeddischarge-neck 2. The contract'ed neck is preferably soldered to thefilter-case, and it serves to prevent splashing of water when thefilter-cylinder is removed from the case. At the upper and lower ends ofthe case are annular outwardly-presented beads 3, that serve to provideannular pockets 4 at the'interior of the case. These pockets receivepacking-rings 5, preferably of rubber, and the interior diameter ofwhich is less than the interior diameter of the filtercase, as seen inFig. I. f

6 designates a filter-cylinder, preferably of tripoli stone, and 7 is aperforated tube eX- tending longitudinally through the saidfiltercylinder.

8 is an end cap, that is tted to the lower vend of the filter-cylinderand secured to the lower end of the perforated tube 7, the said end caphaving a fiange that encircles the stone, as seen in Fig. I'. A gasket 9is preferably introduced -between the end cap and the end of thelter-cylinder.

10 is an upper end cap, that is provided with a flange that encirclesthe upper end of the filter-cylinder yand lis connected tothe perforatedtube, a gasket llbeing preferablyinp troduced between said end cap andcylinder. The upper end cap is also provided with ahorizontallyextending annular flange 12,`

which is adapted to rest upon the upper edge of the filter-case l.

'13 is a discharge-tube, centrally fitted in the upper end cap andhaving communication with the interior of the perforated tube 7 thisdischarge-tube serving as an outlet` through which the filtered waterthat percolates through the filter-cylinder into the perforated tube 7finds escape. to a water-service pipe through any -suitable connectionattached to a nipple la', projecting from the filter-case.

By constructing the filter as describedandl v placing thepacking-rings--I in Apockets in the filter-case, the interior diameterof which is Vless thanthe interior diameter ofthe case, I

ter as the one herein described have hereto-y vfore been made, but inwhich the packing members are carried by the filter-cylinder.

vIn these constructions the lower packing member rides against theinterior of the case when the filter-cylinder vis extracted, andtherefore the water in the space between the filter-case andfilter-cylinder is lifted in a column and discharged over the top of thefiltercase, which is an objectionable occurrence I completely overcomein my filter.

In Fig. III, I have illustrated a modification of my filter in which theessential features of my improvement are present, though thefilter-cylinder `partsvare of different construction. In thismodification, 1 designates the filter-case, having the contracted neck 2at its lower end and provided with the beads 8', containing pockets 4,inwhich the packing-rings 5 areseated. der, in which isthe perforatedtube 7 8 is acement cap that is lapplied to the lower end of thefilter-cylinder, which is cut out to per- PatenteaAug.1,1eo5. f l

The filter maybe united 6 is the filter-cylinmit of the cap ttingthereinto in order that the cement may securea firm hold upon thethreaded end of the perforated tube 7. The pores of the cap are suitablyclosed to prevent seepage of water therethrough. In the center of thiscap is a bushing 8, that receives a nipple 8b, through which thefiltered water finds escape. 10 is an upper pore-sealed cement cap thatis applied to the upper end of the filter-cylinder, which is also cutout to permit of the cap seating therein. The Vcap l0 contains a bushingIO, into which is introduced the shank of a handle 10b, by which thefilter-cylinder may be lifted from its ease. This construction is suchthat, if desired, the filtered Water may be discharged from the upperend of the cylinder, the only change necessary being the removal of thehandle 10b in the introduction of a discharge-pipe similar to that 13and the removal of the nipple 8b and the substitution of a plug to closethe bushing 8.

The packing-rings 5, placed in the filtercase as described, are solocated that they are not susceptible to injury when the filter-cylinderis introduced into its case er removed therefrom and being looselyfitted in the beads of the filter-case may be readily removed Withoutthe employment of any tool and replaced by new ones when they becomeunfit for further use. The rings fit firmly in the beads, and there isno liability of their becoming displaced When the filter-cylinder isremoved to be cleansed. An additional advantage in placing thepacking-rings in the filter-ease instead of applying them to thefilter-cylinder lies in the fact that when the filter-cylinder iscleansed, usually by the process of brushing it, the packing-rings beingentirely absent therefrom are not subjected to the wear that occurs incleansing the cylinder in constructions wherein the packingrings areapplied to the filter-cylinder. A still further feature of advantagelies in the fact that a more perfect lit of the packingrings is secureddueto the water entering the filter-case acting to seat thepacking-rings with greater force into the space between thefilter-cylinder and its case, thereby 'making a more perfect joint thatwill not permit of the water dripping from the filter.

I claim as my invention- In a water-filter, the combination of acylindrical case open at both ol its ends and provided at each end withan outwardly-presented bead forming an annular pocket, a filter-cylinderwithin said cylinder and spaced from the inner wall of the casethroughout its entire height, and a packing-ring in each of said pocketsand engaging said filter-cylinder at points inwardly from the endsthereof.
